Battery won't charge

I am using an IBM-T30. I am running Windows XP SP2. My computer is basically working fine except for one thing. The battery won't charge. The driver that is responsible for that is working fine. I assume that the Ac adapter is working fine seeing that it is powering my machine right now. Does anyone at fixya have any solutions.

Note: When I place the battery in the computer, the battery icon on the keyboard starts flashing. This should mean that the battery is charging but it isn't. Help.....Please??

Additionally, I should add that one day I was using my computer and it suddenly froze. I turned it off. When I tried to start it up it gave me an "1802" error message about the PCI card. The laptop was inactive for about 2 months then I removed the PCI card and placed in back in the computer. After that, the battery hasn't charged once. The battery used to charge up well before the PCI incident. Any solutions??

Ifthe laptop battery is more than 3 - 4 years old then the battery could be wornout. Rechargeable batteries have a finite number of charge and discharge cyclesand will lose their charge capacity over time, i.e. won't charge to 100% andgradually the charge reduces until the battery won't charge up atall.
ORThe battery shows a 100% charge but when the adapter is disconnected thebattery drops off to zero capacity in a very short time.
Ifthe battery drops to an unacceptable charge level then the battery needs to bereplaced.

You should charge the battery longer about four hours. Then the light should be green. Try. If that don't work disconnect the battery and check for anything. Connect your battery again and take a look. If it still isn't functioning please let me know.

there is a switch in the plug end to the back of your comp its like a little swinging door that when you unplug out of back of comp this switch engages battery now if you unplug just from wall its going to see these 2 things the doors not shut but i have to keep working so it sets aside the plug still recognizing it of course but running off the battery trying to still find out why the powers not there but the plug is still plugged in and it will continually search until it reaches its falt point of dead battery
its like a battery backup for your system it gets unplug but wants to know where the power is

now in reference to the little swinging door i call it its a power over relay in your comp for some reason its not closing properly to allow battery to run by self
this is usually just a switch that needs adjusted in the motherboard configuration
